Suggestion: You must pay attention to the problem of scalp pain. I'm happy to answer this question for you: it's normal. Scalp pain is not a disease, but one of the symptoms of other diseases. When you catch a cold, your head will shrink because of the cold and your blood will not flow smoothly. At this time, your nervous system is particularly sensitive, so you will feel scalp pain.
Suggestion: Scalp pain is often local pain, and touching it with your hands is like acupuncture. The treatment method is: wash your hair with hot water, or blow hot air at the painful place with a hair dryer, and gently massage while blowing, which will generally relieve the symptoms in a few minutes.
